Ancient Cambodia has been influenced by the Indian civilization probably since the beginning of the Christian era. The two main religions of India, Hinduism an Buddhism, were practiced by Cambodians. Jean Boisselier noted that the oldest records indicate the presence of Buddhism in Fou-nan did not date not earlier than the V Century. As much as Cambodians were inspired by this influence, they also modified it according to their own character. With regards to religious practices, whether in Hinduism or Buddhism, the ancient Khmers have left behind many works of arts as well as temples, sculptures and household utensils. Some of the temples are in Cambodia, while others are outside the country, mostly in Thailand. These temples are magnificent; such as the temple of Angkor Wat humans built that we have trouble believing.
All these creations are concrete proof that ancient Cambodia already had a glorious civilization in the angkorian period.
